  • 88ee9d571   ext4: support xattr gnu.* namespace for the Hurd ... Browse Code »

    The Hurd gained[0] support for moving the translator and author
    fields out of the inode and into the "gnu.*" xattr namespace.

    In anticipation of that, an xattr INDEX was reserved[1]. The Hurd has
    now been brought into compliance[2] with that.

    This patch adds support for reading and writing such attributes from
    Linux; you can now do something like

    mkdir -p hurd-root/servers/socket
    touch hurd-root/servers/socket/1
    setfattr --name=gnu.translator --value='"/hurd/pflocal\0"' \
    hurd-root/servers/socket/1
    getfattr --name=gnu.translator hurd-root/servers/socket/1
    # file: 1
    gnu.translator="/hurd/pflocal"

    to setup a pipe translator, which is being used to create[3] a
    vm-image for the Hurd from GNU Guix.
